How to detect gravity/gees

[Tompete Kerman]

I'm attempting to find a way to read the surface gravity of the body I'm orbiting.
The API reference says that the GeeASL of Kerbin should be 9.81, but when I read it at the launchpad or in orbit around Kerbin, it reads as "1.00034160493135"

Should I just multiply the result by ~9.8, or is there a more accurate method of getting the number I need?

I believe the unit of that value is Earth surface gravities, like when people say "An untrained individual not used to the g-straining maneuver can black out between 4 and 6 g, particularly if this is pulled suddenly.", hence 1.000 at Kerbin.

... in fact, that's what the old copy of the API says:

"The gravitational acceleration of the body at sea level, in units of gees (1 gee = 9.81 m/s^2)"

So if I'm trying to get the gravitational acceleration pulling me downwards, I'd need to get the vector3 of that and isolate the proper axis?

Only if you're exactly at sea level.

I haven't tested it, but what you're talking about looks like it would be Vessel.graviticAcceleration.

Look at the "CeletialBody.gravParameter" 

this is the standard gravitational parameter: (my) 

now for a pysics session: F = /(my) * m) / r^2 

for the normal gravitation m is 1 and r is CelestialBody.Radius. (or the terrain altitude but this is negletable)
